How to use the sqrt () method to calculate the square root in Python

This article describes how to use the sqrt () method to calculate the square root in Python. it is a basic knowledge of Python learning. For more information, see sqrt () returns the square root of x (x> 0 ).
Syntax

The syntax of the sqrt () method is as follows:

Import mathmath. sqrt (x)

Note: This function cannot be directly accessed. Therefore, we need to import the math module and then use the static object of math to call this function.
Parameters

• X -- this is a numeric expression.

Return value

This method returns the square root of x, for x> 0.
Example

The following example shows how to use the sqrt () method.

#! /Usr/bin/pythonimport math # This will import math moduleprint "math. sqrt (100): ", math. sqrt (100) print "math. sqrt (7): ", math. sqrt (7) print "math. sqrt (math. pi): ", math. sqrt (math. pi)

When we run the above program, it will produce the following results:

Math. sqrt (100): 10.0math.sqrt (7): 2.64575131106math.sqrt (math. pi): 1.77245385091
